Hey,
I'm the developer of Multifl0w - someone referred me to this thread a while ago but I'm just now getting to posting in it. I believe the recent update has fixed most of the issues, but I'm still getting a few reports of crashes. I have absolutely not been able to get any of my devices to crash at all after the update - if you're still crashing, please please send a syslog to support(at)multifl0w.com. I've been extremely busy with support emails and such, but I still haven't been able to replicate any crashes on my devices. Maybe Multifl0w is conflicting with other tweaks, I'm not sure. My number 1 priority is to eliminate all crashes - it's best to do that before trying to add more features. I did the icons thing because it made sense, and it wasn't too hard to do, and I liked the idea. (And it was probably the most requested feature). I'm several days behind on emails and probably will be for a while, but if you have questions/comments/concerns/complaints/whatever, let me know at that email address. I'll respond as soon as I can.
